Police looking for a 29-year-old Colorado mom who's been missing since Thanksgiving are hoping that newly released surveillance video showing her last sighting at a grocery store will help in finding her.

Kelsey Berreth, who was reported missing by her mother on Dec. 2, was last seen in public with her 1-year-old daughter at a Safeway supermarket on Nov. 22 in Woodland Park, where she's lived since 2016.

Patrick Frazee, Berreth's fiance, told police he saw Berreth Thanksgiving afternoon when they exchanged their daughter, police chief Miles De Young said Monday. Frazee is taking care of the young girl now at his home.

Frazee and Berreth were planning to marry and had been living in separate homes. Berreth would either sleep at Frazee's house or take the child to her home.

Frazee told police he took care of the child during the day while Berreth worked as a flight instructor at Doss Aviation. Berreth's employer got a text from her phone Nov. 25 saying she needed to take off the upcoming week. Her phone was tracked as being 700 miles away in Gooding, Idaho, that day.

De Young said Frazee is cooperating with police and is not a suspect in the case. Berreth's fiance could not be reached for comment by NBC.

Frazee's attorney confirmed in a Wednesday statement that his client is cooperating and added that Frazee voluntarily turned over his phone.

"Mr. Frazee hopes and prays for Ms. Berreth's return. Mr. Frazee will continue to cooperate with law enforcement and continue to parent the child he shares with Ms. Berreth," the statement read.

"At this point, he is the father of Kelsey's daughter, and we're gonna leave it at that," De Young told reporters. "So, this is a missing person's case."

Cheryl Berreth, Kelsey Berreth's mother, said at a press conference that "this is completely out of character" for her daughter.

"She loves her family and friends, and she loves her job," Cheryl Berreth said. "Kelsey, we just want you home. ... We won't quit looking."
